Lattice dynamics in the FeSi-based family of superconductors
Samar Layek, Mads Fonager Hansen, Jean-Baptiste Vaney +5
The lattice dynamics of the superconducting materials LaFeSiH and LaFeSiO as well as their intermetallic precursor LaFeSi are investigated by polarized Raman spectroscopy and first…
Superconductivity in the crystallogenide LaFeSiO with squeezed FeSi layers
M. F. Hansen, J. -B. Vaney, C. Lepoittevin +10
Pnictogens and chalcogens are both viable anions for promoting Fe-based superconductivity and intense research activity in the related families has established systematic correlati…
Thin-film aspects of superconducting nickelates
F. Bernardini, L. Iglesias, M. Bibes +1
The discovery of superconductivity in infinite-layer nickelates has attracted much attention due to their association to the high- cuprates. Cuprate superconductivity was firs…
Single-layer T'-type nickelates: Ni is Ni
F. Bernardini, A. Demourgues, A. Cano
The discovery of superconductivity in the infinite-layer nickelates has opened new perspectives in the context of quantum materials. We analyze, via first-principles calculations,…
Nickelate superconductors: an ongoing dialog between theory and experiments
A. S. Botana, F. Bernardini, A. Cano
After decades of fundamental research, unconventional superconductivity has recently been demonstrated in rare-earth infinite-layer nickelates. The current view depicts these syste…
Ab initio many-body GW correlations in the electronic structure of LaNiO
Valerio Olevano, Fabio Bernardini, Xavier Blase +1
We present an ab initio self-energy calculation of the electronic structure of LaNiO. With respect to density-functional theory we find that in the La 4 states und…
Stability and electronic properties of the LaNiO/SrTiO interface
F. Bernardini, A. Cano
Infinite-layer nickelate thin films materialize an intriguing new platform for high-temperature unconventional superconductivity, with LaNiO/SrTiO as reference setup. We di…
Magnetic penetration depth and in superconducting nickelates
F. Bernardini, V. Olevano, A. Cano
We compute the nominal magnetic penetration depth of NiO ( La, Nd) from first principles calculations and discuss the results in relation to the superconducting .…
Evidence of nodal superconductivity in LaFeSiH
A. Bhattacharyya, P. Rodière, J. -B. Vaney +7
Unconventional superconductivity has recently been discovered in the first iron-based superconducting silicide LaFeSiH. By using the complementary techniques of muon spin rotation,…
Elasticity-driven attraction between Abrikosov vortices in high- superconductors: Leading role of a non-core contribution
A. Cano, A. P. Levanyuk, S. A. Minyukov
We show that the strain-induced attraction between Abrikosov vortices has a non-core contribution overlooked up until now. This contribution is an example of the universal mechanis…
